abstract="Background and aims: Resistance of bacteria against antibiotics has always been a prevalent problem in medicine. So, finding new antimicrobial compounds with least side effects seems to be necessary. This paper aims to explore the antimicrobial effects of Thyme, and Aloe vera and Zararia multiflora extracts against Pseudomonas aeruginosa resistant to antibiotics.
Methods: Thyme, and Aloe vera and Z. Multiflora extracts were obtained by using rotary devices. Twenty samples of P. aeruginosa were collected from the patients being cured in Zabol hospitals. The least hindering and killing concentrations of the samples were calculated by lowering their density in sinks. Sensitivity of P. aeruginosa to the different antibiotics prepared by Padtan Teb Co was evaluated by the diffusion disk standard method proposed by Kirby Bauer. Data were analyzed statistically by determination of significant difference using analysis of variance (ANOVA) test. All tests were analyzed at the significance level P<0.05.
Results: Our results have shown that Aloe vera hinders the growth of bacteria in various concentrations. Despite the relative resistance of most of the samples in the used concentrations, the highest sensitivity was observed in 10 and 20 mg/l. Approximately, Aloe vera extract has shown the highest hindrance effect in 5 mg/l. Further, the highest sensitivity to Z. Multiflora was in 10 and 20 mg/l in which 100% of the bacteria were killed. Approximately, Z. Multiflora of 5mg/l had the highest resistive effect.
Conclusion: Thyme, and Aloe vera and Z. Multiflora extracts have considerable antimicrobial effect on the samples of the P. aeruginosa resistant to antibiotics.",

title="The effects of essential oils, extracts and powder of Satureja bachtiarica bung on the bacterial growth of Staphylococcus aureus in cream cheese",

abstract="Background and aims: Staphylococcus aureus is an important contaminant of milk and dairy products. It can cause a wide range of illnesses including, food poisonings and nosocomial infections. The aim of this study was to compare the antimicrobial effects of the essential oil , aqueous extract and powder of the Satureja bachtiarica on staphylococcus aureus. Methods: Satureja bachtiarica was collected from the heights of the province of Chaharmahal va Bakhtiari and its extract and essential oil were collected. The bacteria staphylococcus aureus was obtained from the Iranian Research Organization for Science and Technology. The bacterium was inoculated in equal amounts to specimens of cream cheese; afterward different concentrations of the essential oil , aqueous extract, and herbal powder were produced and inoculated in in equal amounts to the cream cheese specimens; subsequently, the specimens were checked 20, 40 and 60 days after inoculation. In the end, the microbial activity of the essential oil , aqueous extract and herbal powder were reported according to mg/ml. Results: The minimum growth of the bacteria staphylococcus aureus was observed in the 1000 milligram concentrations of essential oils and 125 mg of the aqueous extract and 125 mg of powder of the plant. At all the concentrations tested the pH changes in the fortieth day, and the changes in the rigidity of the cream cheese specimens were significant as well. At some of the concentrations of the aqueous extract and some concentrations of the herbal powder the changes in the texture of the cream cheeses, comparing to the controls, were significant. Conclusion: The essential oil , aqueous extract and powder of the Satureja bachtiarica have a great inhibiting effect on the growth of the bacterium staphylococcus aureus. Thus, it can be used as a natural preservative in foods with high lipid content.",

title="Preliminary phytochemical, pharmacognostic and physicochemical evaluation of leaf of Gomphrena serrata",

pages="16-25",
abstract="Background and aims: To analyze the pharmacognostic characteristics and physiochemical parameters of the leaves of Gomphrena serrata (G. serrata). Methods: Microscopic characters and powder analysis had been carried out with the help of a microscope. The physiochemical properties such as loss on drying, total ash value, acid insoluble ash value, water soluble ash value, extractive values and fluorescence of G. serrata had been performed. Results: Macroscopically, the leaves are simple, elliptical in shape, rounded or obtuse apex with an entire margin. Microscopically, the leaf showed the presence of epidermal cells with uniseriate multicellular covering trichomes and anomocytic stomata, followed by 1-2 layered collenchymatous cells and 10-15 numbered conjoint, collateral closed vascular bundles are some of the diagnostic characteristics observed from an anatomical study. Powder microscopy of leaf revealed the presence of uniseriate multicellular covering trichomes, lignified xylem vessels, epidermis with anomocytic stomata and parenchyma cells. The investigations also included leaf surface data i.e., quantitative leaf microscopy and fluorescence analysis. Physiochemical parameters such as loss on drying, extractive values and ash values were also determined. Preliminary phytochemical screening showed the presence of flavonoids, alkaloids, tannins, steroids, carbohydrates, glycosides, amino acids and proteins. Conclusion: The morphological, microscopical and physicochemical parameter results provided in this paper may be utilized as a basis for the preparation of a monograph on G. serrata leaves. ",

abstract="Background and aims: Coinciding with the rise of human population, the use of medicinal plants began by ancient peoples as medicine, poison, detergent, food and paint upon it. Methods: In present study, the chemical composition and antioxidant activity of Shirazi thyme, T. vulgaris, essential oil was analyzed by three methods (DPPH, potassium ferricyanide reaction and CUPRAC methods) and comparison with TBHQ method for determination of reducing power of T. vulgaris essential oil by potassium ferricyanide method. Phytochemical composition of T. vulgaris essential oil was identified by GC/Mass device. Results: The results showed that T. vulgaris essential oil has a good potential against oxidants even near to TBHQ. The essential oils of this plant are Thymol (40.02%) and Carvacrol (18.31%). Conclusion: The results of antioxidant activity of Thymus vulgaris using three methods and comparison with TBHQ (Tertiary butyl hydroquinone) showed Thymus vulgaris essential oil have a good potential for scavenging of free radicals similar to TBHQ.
